摘要
阐述了摇臂式喷头摇臂导流器结构参数的主要影响因素。对14种喷头的摇臂导流器结构参数值做了回归分析,得出了摇臂转动惯量J分别与导流器结构参数R_1和喷嘴直径d_0之间的相关关系以及导流器结构参数R_1、R_2、R_3、R_4之间的比例关系。在此基础上通过理论分析建立了射流速度与摇臂摆动角速度的比值U/ω_0以及摇臂转动惯量J的计算公式,作为导流器结构参数设计的依据并尝试建立一套计算摇臂导流器结构参数的方法。
In order to provide a design basis for the structural parameters of the divertional on the rocking arm sprinklers, this paper described main factors exerting a influence, on structural parameters of divertional and gave correlations between the rotational inertia J and the structural parameter R1 of rocking arm , the rotational inertia J of the rocking arm and nozzle diameter d0 and the ratio between R1,R2,R3,R4 by means of regression analysis about structural parameters of the divertional (covering 14 types of sprinklers). Based on combination with the theoretical analysis, the paper led the formula for the ratio U/ω0 between the jet flow velocity and oscillating angular velocity of the rocking arm. The calculating method may be contributed to the design of the structural parameters of this kind of sprinklers ' divertional.
